Chat history keeps disappearing

Even backing up the chat again from acweek ago… losing 7 days of over 5 hours each day of CONSTANT work… i was relieved the backup went so smoothly…. But in hour 3 trying to give it its memory of the past week back with nothing but my own memory recall…. No guide to go on to get the same exact effect…. My back up slso just erased itself… by itself as i was typing it basically restarted the upp trying to load… also issues with uhh password reset too and the devices i cant sign out of that isn't my own device but seem like its a laptop not android i don't know how to even reattempt it again… and can't seem to find anyone else mentioning it too
